Family bathrooms and ensuites in Castle Hill
Castle Hill is big blocks and big houses — brick veneer from the eighties and nineties, double-storey family homes through the 2000s, and newer estates on the edges. That changes what a renovation looks like. Most jobs here are not one bathroom, they are a main bathroom, an ensuite and often a powder room, and the family cannot lose all of them at once. We stage the work so there is always a working shower in the house, which usually means finishing the ensuite before the main bathroom is opened up. Upstairs bathrooms bring their own demand: the membrane is sitting directly above a living room or kitchen, so waterproofing is checked and photographed before a single tile goes down. Anything structural, or any new wet area where there was not one before, goes through The Hills Shire Council and we handle that paperwork rather than leaving it with you.
We prepare the renovation bylaw paperwork North Sydney strata committees expect — scope of works, contractor insurances, waterproofing methodology — and schedule the noisy stages inside permitted building hours. Membranes go down to AS 3740 with proper cure time and the installation is documented for the strata record, which also protects you at sale.
The other Castle Hill specialty is making small rooms work. Wall-hung vanities, recessed niches, frameless or sliding screens and considered lighting reliably make a three-by-two metre apartment bathroom feel far larger, and designing around the building's existing plumbing stacks keeps both cost and approvals simple.

Bathroom renovations in Castle Hill — questions, answered
How much does a bathroom renovation cost in Castle Hill?
Cost depends on the size of the room, any layout changes and the finishes you choose. After a quick site visit in Castle Hill we give you a fixed, itemised quote, so you know the price before any work starts.
How long will my Castle Hill bathroom renovation take?
Most bathrooms take around 3–4 weeks on site. We give you a schedule before we start and keep you posted at each stage.
Do you handle waterproofing and council approvals?
Yes. Waterproofing is done to Australian Standard AS 3740 with proper cure time, and we manage the licensed plumbing and electrical work plus any The Hills Shire Council requirements your job needs.
Which areas near Castle Hill do you cover?
We work right across the the Hills district and all of Sydney, including North Sydney, Mosman, Hunters Hill.
Can you renovate two bathrooms without leaving us without a shower?
Yes, and in Castle Hill that is how we usually plan it. The ensuite is finished and signed off first, the family moves across to it, then the main bathroom comes out. It adds a little time overall, but nobody is showering at a neighbour's place for three weeks.
Do you handle upstairs bathrooms above living areas?
Regularly. The difference is in the waterproofing and the substrate — the membrane is photographed at every stage and given full cure time before tiling, because a leak above a ceiling is a far more expensive problem than one on a slab.
